Be it known that I, Smears ll BELL, a citizen of the United ice,residing at the city Louis, State of Missouri, United States ofiiiiiericc, have invented a certain new Eul. llncoupling Device forRailway-Cars. of which he following is such a full, cl ar, and exactscription as will enable 1 y one Slill the art to Which. it eppertcinsto make some, reference being had ing drawings torrning perto3; cation.

My invention relates to :1 i. LillCO vice for reilwey cars, and

theprocluction of :1 device in which o si" link 18 used to connect theuuceuphi r lever and the locking pin of the coupler heat in Which thelink is prov end with a head prcven its passage l, and

through the eye oi the coupler lock. 42. other object of my ii'weiit anis to prm forms of brackets for carrying the UPFLt1i1'- rod.

In previous forms of uncoupling devices, a. for instance that shown. inmy prior listen No. 1,159,470, granted Nmeinbcr 9 1915, the lower end ofthe link connecting the coupling rod to the locking pin has been providecl with an open loop adapted to pass through the eye of the lockingpin. ln. such devices, While the open loop cannot he disengaged from thecoupler pin while the parts are in lion 1 p0 upon the this is notapparent to it e ordii' i;y rziilw 3; employees, and I have found inpractice that they bend these loops into closed position, thuspreventing the removal of the parts in the manner intends ll. this ofthe objects of my invention, therefore, to pro vicle a link in such formthat this will not occur.

In the accompanying drawings, which illustrate some forms of uncouplingdevice made in accordance with my invention, Figure 1 is a frontelevation; Fig. 2 it top plan preferred. form of link; Fig lsometrlcpro]ection ol' the inn carrying the coupling .i'od; l to. 5 culergeddetail View of the outer hracl'et :t'or

Formed on the forward onis an eye 20 adopted to eugege -with the upper cud oi": e liulc Ql.'lhis link 21 is provided at its upper end with an over-turned portion252, and at its lower end with a bend or loop terminating in e heed Q-l,which is ll'littlfi of such size that it cannot pass through the eye llof the locking pin 13. Consequently in placing the parts in position theend oi. the linlc 2]. must he first threaded through. the eye 14:, andafterward 1 20 While the rod is out of normal positioiu :1 mil when therod is in normal position in the brackets l8, 19, the link cannot becomedetached. ltis evident that the lower eutl oi? the link cannot become(lisciigzigeil from the eye Li, and consequently there will be no cpgmrentreason for closing; the loop it will also be evident that thedevice will not operate it the upper loop is closed, and therefore therewill be no inclinutioii on the part cl? a railway employee mutilate thedevice by bending); it.

in 9 l have shmvn inofified form of linli: i i which the lower loop sois made in it dill it form. from that shown in Fig. 3, and the head itis replaced lvy a, head 25 formed by bending; the metal oi? the linkinto it l circle. ln strengthen the loop c;

form prefer to pset'ting; a, portion of n in which the lower loop 23 issimilar in form to that shown in Fig. 9, but the head 24 is of the sameform as shown in Fig.3. 'Hi Figs. 12 and 13 I have shown a still furthermodification of the link, in which the upper end of the link in place ofbeing formed by a turned over portion, as in Fig. 3, is provided with aspiral loop 27.

The bracket 18 which supports the inner end of the rod 15, is shown indetail in Fig. 4. This bracket consists of a plate 30 adapted to besecured against the front end of the car. Projecting forwardly from thisplate 30 is a plate 31. The plate 31 has a portion 32 cut around threesides and bent down so as to form a bearing for the rod 15.

The plate 31 is also bent, as shown in Figs.

2 and 4:, so that two short arms 33 are formed, which project over therod 15 and are spaced so far apart laterally that when the rod is turnedinto a position substantially at right angles to its normal position,the rod may be lifted out of the bracket. The bracket 19 which supportsthe outer end of the rod 15 is provided with removable means forsecuring the rod in position. In the forms shown in Figs. 2 and 5 aplate 35 is secured against the end of the car, which plate hasforwardly projecting sides 36 forming a bearing for the rod, and a plate37 passing over the top of the rod. Plates 36 and 37 are both providedwith openings 38 through which passes a cotter-pin. 39,

thus removably securing the rod in position.

It will be evident that by removing the cotter-pin 39 and swinging thetop of-the rod through at an angle of substantially 90 it can be liftedfrom the bracket 19, hereinbefore described. In Figs. 6, 7, 8 14, 15 and16 are shown various modifications of the outer bracket. In each ofthese the plate. 35 is adapted to be secured to the end or some otherpart of the\car, while'the plate 36 forms a bearing for the rod. In theforms shown in Figs. 7, 8, 141, 15 and 16 the holes 38 and. cotter-pinare arranged so that the cotter pin passes over the rod 15 in place ofat one side of it, as in forms shown in Figs. 2, 5 and 6. The action ofall, however, is substantially the same. Each provides an elongatedbearing for the rod, and has removable means for holding the rod inposition. The forms shown in Figs. 14 and 15 are especially adapted tobe secured to the end sill of the car. The form shown in Fig. 16provides a double bearing which may be reversed.

The operation of my device will be clear from the foregoing description.In securing the parts in position, the end 22 of the link is threadedfirst through the eye 14 of the locking-pin and then through the eye 20of the rod 15 while the rod is out-of position with respect to thebrackets. The rod is then swung around into a position to pass betweenthe two arms 33 of the bracket 18,
